3. SERVICING THE 9Z
3.1. User
Password
If you have forgotten the user password for your 9Z you can use the Service and Test
Menu to display the password, instead of having to reset it through a hard reset of the
transmitter. You will need a Service and Test Menu enabler to access the information
(see Section 6.2 and APPENDIX A)
The user password can be found on the “System Overview” screen of the Futaba Test
and Service Menus. This is fully described in the diagram in Section 6.3.
3.2. 9Z Transmitter Calibration
It is a good idea to recalibrate your transmitter after a few years of use as the hardware
settings drift. Typical symptoms include servo neutral positions ‘jumping’ at low rates and
sometimes even switches failing to work in one position.
You can test if your transmitter needs recalibration of its joysticks in the following way:
1.
Start by selecting a blank (freshly reset) airplane program.
2.
Go to the ATV menu
3.
Hold both sticks fully up and fully right while switching between AIL, ELE, THR and
RUD. If the pointer below the graph moves even a little while you are switching
channels you radio needs calibration.
4.
Repeat step 3 but now holding both sticks fully down and fully left.
5.
Finally, repeat step 3 with both sticks cantered (including throttle axis).
To recalibrate your transmitter you’ll need to access the Futaba Service and Test Menu.
This is described in Section 6 (The Futaba Service and Test Menu) and you should refer
to the listed Joystick and Switch recalibration menus for the recalibration procedure.
3.3. Replacing Corner Switches
This procedure relates to a like for like replacement of the Corner Switches. If you wish
to modify a switch (e.g. replace a 2 position switch with a 3 position) you should refer to
Section 4.1 (Adding extra 3 position switches).
1.
Disassemble the 9Z’s case to Stage 3 as described in Section 5 (Disassembling and
Reassembling the 9Z’s Case).
2.
Disconnect the ribbon cables from the corner switches.
3.
Remove the switch from the corner panel by unscrewing the retaining plate
4.
Desolder the switch from its mini-PCB
5.
Replace with a 9Z switch and solder it to the mini-PCB
Note: The 9Z switches do not have an offset connector pattern like those of the 8U
series, the 8U series switches will fit but they require some gentle bending of the
connectors see Figure 9.
6.
Reassemble is a reversal of disassembly
